Description

【発明の詳細な説明】コネクタ発明の背景１．発明の分野：本発明は、電気コネクタ、特に、カードエッジコネクタに関する。２．従来技術の簡単な説明：プリント基板の前縁部が絶縁ハウジングの長手方向溝内に挿入される種々のカードエッジコネクタが当該技術分野において知られている。この溝の近部に、溝に近接して並置された円弧状導電部を有する複数のコンタクトが配置され、基板が溝内に挿入されたときに、プリント基板の導電性パッドがコンタクトの円弧状部に接触する。このエッジカードコネクタは、プリント基板をコネクタ内にロックするラッチを用いてもよい。この構造の場合、プリント基板は、コネクタ内に強固に取付けられなければならない。従って、配線基板をコネクタ内に強固かつ効率的に取付けるためのラッチに対する改善が常に要請されている。この装置において発生する可能性のある他の問題は、プリント基板が溝内に挿入されたときに、コンタクト部材が過度の応力を受け、その結果、垂直方向の接触力が失われるということである。従って、コンタクト部材のこの過度の応力を防止する手段が必要とされている。他の問題は、ハウジングに不適当な応力を与えずかつコンタクトをハウジングから外すように押圧しようとする力に抗する態様で、多数の並置されたコンタクトが、ハウジング内に挿入されかつその中に強固に保持されなければならないという事実に関連する。従って、ハウジング内でコンタクトを最適に挿入かつ保持する手段が必要とされている。発明の概要本発明のカードエッジコネクタでは、ラッチ機構が、絶縁ハウジングの各側部に設けられ、プリント基板を所定位置に固定する。これらのラッチ機構は、絶縁ハウジングの直立部に枢動可能に結合され、円弧状に枢動して絶縁ハウジングの直立端部の上側のタブに係合する。これらの垂直タブは、プリント基板の対向側に配置され、ラッチ機構が所定位置に枢動したときに、ラッチ機構の平行なフィンガは、絶縁ハウジングの垂直部の上方に延びるタブを互いの方向に向けて押圧し、内方に向く側方の力をプリント基板に作用させて所定位置に固定する。本発明のカードコネクタでは、各コンタクトの基部から上方に延びる垂直プレートも設けられている。このプレートは、コンタクトの円弧状部の末端部に対向する上面を有し、プリント基板がコンタクトに係合したときに円弧状部の過度の応力を防止する。各コンタクトのプレート部に、対向した長手方向凹部を有する長手方向突起も設けられている。これらの突起のそれぞれは、ハウジングの溝に係合して、コンタクトを最初に挿入したときに、長手方向に沿って案内する作用をなす。この突起は、ハウジングと協働して、最終挿入後にコンタクトをハウジング内に保持する。図面の簡単な説明添付図面を参照して本発明について、更に説明する。第１図は、本発明のエッジコネクタの好ましい実施の形態の側部立面図であり、第２図は、第１図に示したエッジコネクタの平面図であり、第３図は、第１図に示したエッジコネクタの端面図であり、第３Ａ図は、第２図中で円で囲ったエッジコネクタの底部の拡大図であり、第３Ｂ図は、第３Ａ図の線Ｖ−Ｖに沿う断面図であり、第４図は、第２図の線ＩＶ−ＩＶに沿う断面図であり、第５図は、エッジコネクタの他の部分をより良く示すために１のラッチ機構が取り外された第１図に示したエッジコネクタの斜視図であり、第６図は、本発明のエッジコネクタで使用されるラッチ機構の側面図であり、第７図は、第６図に示したラッチ機構の正面図であり、第８図は、第６図に示したラッチ機構の背面図であり、第９図は、第６図に示したラッチ機構の平面図であり、第１０図は、第６図に示したラッチ機構の底面図であり、第１１図は、第６図中の円ＸＩ内の領域の詳細図であり、第１２図は、第６図に示したラッチ機構の斜視図であり、第１３図は、第１図に示したコンタクト部材の１の側部立面図であり、第１４図は、第１３図に示したコンタクト部材の端面図であり、第１５図は、第１３図に示したコンタクト部材の斜視図であり、第１６図は、本発明のプリント配線基プレートエッジコネクタの好ましい実施の形態の側部立面図であり、第１７図は、第１６図に示したエッジコネクタの平面図であり、第１８図は、第１６図に示したエッジコネクタの端面図であり、第１９図は、第１７図の線ＸＩＸ−ＸＩＸに沿う断面図であり、第２０図は、第１６図に示したエッジコネクタで使用されるコンタクト部材の側部立面図であり、第２１図は、第２０図に示したコンタクト部材の端面図である。好ましい実施の形態の詳細な説明第１図から第７図を参照すると、エッジコネクタは、モールド成形された絶縁ハウジング１０を含み、このハウジングは、その上側部１６の溝１５で結合された第１端部１２と第２端部１４とを有している。また、このハウジングは、下側部１８と第１横方向側部２０と第２横方向側部２２とを含んでいる。プリント基板は、その全体を符号２３により、仮想線で示してある。この基板は、ハウジングの溝に係合する前縁部２４と、これに対向する上縁部２５と、第１側縁部２６と、第２側縁部２７とを有している。この前縁部は、基板載置部２８上に支えられる。プリント基板は、縁部２４の各側に沿って配置された導電性パッド（図示せず）を有している。符号２９，３０で示す列（第２図）が、溝１５の対向側に配置されている。各コンタクトあるいは端子２９又は３０は、導電性パッドの対応する端子と電気接続部を形成する。ハウジングの下側部から、符号３２，３４で示すリードと符号３６，３８で示す導電性位置決めピンとが延び、これらの双方はマザーボード（図示せず）に係合する。また、ハウジングは、溝１５に整合しかつこの溝とほぼ同じ幅の溝４１を有する第１直立部材４０と、同様に溝１５に整合しかつこの溝とほぼ同様な幅の溝４３を有する第２直立部材４２とを含んでいる。タブ４４，４６が、部材４０，４２のそれぞれから延びている。また、溝４１，４３は、これらのタブを垂直方向に貫通する。また、ハウジングは、ハウジングがマザーボードに係合したときに、マザーボードで支えられる符号４８，５０で示したスタンドオフを含んでいる。最後に、エッジコネクタは、全体が符号５２で示されている第１ラッチ部材と全体が符号５４で示されている第２ラッチ部材とを含んでいる。第５図を参照すると、各タブ４４，４６は、例えばタブの前縁部の近部に延びるリブ４６Ａ，４６Ｂのような立上がりリブを有している。直立部材４０，４２は、それぞれ、部分４５Ａ，４５Ｂを有するスプリットウエブ４５を含んでいる。このウエブは、各直立部材４０，４２の対向部が互いに近接する方向に及び離れる方向に移動可能なように、割れている。直立部材４０，４２の内面に、ラッチ機構の突起６６，６８を受入れる大きさの一対のＶ字形状溝４７が、ウエブ４５に近接して配置されている。第６図から第１１図を参照すると、これらのラッチ機構のそれぞれは、上側シャンク５６と下側エジェクトフック５８とを含んでいる。上側シャンクに側方枢動突起６０，６２が設けられ、この突起により、ラッチ機構は、絶縁ハウジングの孔に取付けられる。また、ラッチ機構は、長手方向リブ６４と側方係合突起６６，６８とフィンガ７０，７２と側方タブ７４，７６とを含んでいる。ラッチ機構のそれぞれは、突起６０又は６２上を、プリント基板に係合する位置から基板から外れた後方の傾斜位置に枢動する。ラッチがその後方の外れた位置にあるときに、プリント基板は、その前縁部が溝１５に係合しかつその側縁部のそれぞれが垂直部材４０，４２の溝４１，４３に係合するように、ハウジング内に挿入される。ウエブ４５が割れているために、溝４１，４３は、基板の厚さより僅かに幅広で、基板はコネクタ内に容易に滑り込む。プリント基板がスロット１５内に押込まれると、基板の縁部２４は、各ラッチのエジェクトフック５８に係合してラッチを突起６０，６２上で枢動させる。ラッチが枢動したとき、フィンガ７０，７２がタブ４４，４６上を摺動する。フィンガ７０，７２は、タブ４４，４６の立上がりリブ４４Ａ，４６Ａに係合し、これらのタブを内方に案内し、これにより、溝４１，４３の縁部がプリント配線基プレートの対向した横方向側部に押圧されかつこの側部でクランプされて、プリント基板をコネクタ内に強固に保持する。ラッチが閉位置に移動すると、突起６６，６８は溝４７内に嵌合し、各ラッチは、閉位置でロックされる。また、ラッチ機構は、全体が符号７８で示されたヘッド部を含んでいる。ロック位置において、ヘッド部の前部ノーズ８０は、プリント基板の凹部に係合し、基板は適切に配置されかつ所定位置で固定される。ラッチ機構は、通常は、フィンガタブ８２により操作され、ラッチを回転しかつコネクタから基板を排出する。第１３図及び第１４図を参照すると、コンタクト部材のそれぞれは、垂直部８４と円弧状部８６とこの円弧状部の末端部８８とを含む片持ち状コンタクトアームを含んでいる。この垂直部は、基部９０から延び、この垂直部から反対方向に、リード９２が基部から延びている。また、端子をハウジング１０内に装着するための支持プレート９４が、基部から側方及び垂直方向に延びている。好ましくは、支持プレート９４から打抜き加工された細長い突起９６が、支持プレートの側部から延び、支持プレートの反対側に凹部９８が設けられている。円弧状部の末端部に対向する位置において、支持プレートは、この支持プレート９４の縁部に形成された末端部支持面１００を有している。この面の目的は、プリント基板が絶縁ハウジングの溝内に挿入されたときに、円弧状部の過度の応力を防止することである。面１００と末端部８８の先端との間の間隙は、基板挿入の結果として先端部が移動したときに、コンタクトアームの永久変形が生じる前に先端部が面１００に当接するような寸法を有している。また、支持プレートの外縁部９５は、上縁部の保持突片１０３と下縁部に沿う位置決め面１０６とを有する凹設面１０２を有している。第１３図から分かるように、突片１０３は、突起９６の長手方向長さの中間の支持プレート９４に沿う位置に配置される。コンタクト２９，３０のそれぞれは、コネクタ１０のハウジングの複数の端子あるいはコンタクト凹部１０７の１内に受入れられる。各凹部１０７は、この凹部の側壁の１内に延びる溝１０８を含んでいる。この溝の幅ｗ（第３Ｂ図）は、突起９６の幅ｔより僅かに幅広である。突起９６の上部を位置決めする寸法ｓは、コンタクトが最終位置にあるときに、突起９６の上部が溝１０８の上部に配置されるように定められるのが好ましい。溝１０８は、底面１８から上面１６に向けて延び、基板受入れ溝１５内に基板２３を挿入する方向にほぼ整合している。突起９６と溝１０８は、下記の態様で相互に作用する。コンタクト２９，３０に、ハウジング１０内に挿入するための力が作用するときに、これらのコンタクトは、溝１０８内に突起９６を挿入させて配置される。溝は突起より僅かに幅広であるために、突起は、突片１０３が基板レスト２８に係合するまで、溝内を摺動する。突起の高さｈを適切な寸法にすることにより、突起の長手方向外面は、溝１０８の底面で軽く支えられて、比較的小さな側方に向く力を生じ、支持プレート９４の対向側を、溝１０８に対向する凹部１０７の側壁で支える。側方の力の結果として、軸方向の十分な保持力が生じ、最終組立て前に端子をハウジング内で保持する。最終組立て後、この保持力と突片１０３により形成される保持力との組合せ効果により、コンタクトは、ハウジング内に強固に保持される。この保持は、コンタクト列に沿って累積しかつハウジングの歪みを生じることがある側方の大きな力をハウジングの長手方向軸線に沿って発生することなく、達成される。突起９６と溝１０８との間の協働作用により、コンタクトが仮位置決めされ、最終挿入のために適切に配置される。これは、特に、手動で挿入するのに有用である。全コンタクトがこのように装填されたときに、例えば、エアシリンダを使用する最終挿入ステップを使用して全コンタクトを最終位置の各凹部１０７の最終位置に押込むことができる。最終位置において、位置決め面１０６が、基板載置部２８の段部２８ａに配置される。中空突起９６は、その端部が支持プレート９４に結合される簡単な支持構造体として観察可能であることが理解されるべきである。細長い突起は、制限された側方の力を与え、これにより、コンタクトが、歪みを生じさせることがある応力をハウジングに与える危険性を制限する。第１６図から第１９図を参照すると、エッジコネクタの第２の実施の形態は、第１端部２１２と第２端部２１４とを有するモールド成形された絶縁ハウジング２１０を含み、これらの端部はその上側２１６の溝２１５により結合されている。このハウジングは、第１横方向側部２２０と第２横方向側部２２２とを含んでいる。基側部２１８を有する直角部２２１がハウジングの下側に延びている。全体が２２３で示されているプリント基板が仮想線で示されている。この基板は、ハウジングの溝に係合する前縁部２２４と対向する上縁部２２５と第１縁部２２６と第２縁部２２７とを有している。この前縁部は、基板載置部２２８上で支えられる。通常の場合と同様に、プリント基板は、２２９，２３０で示されているコンタクト部材に接続された導電性パッドを有し、これらのコンタクト部材は、溝の対向側に配置されている。直角部の基側部から、２３２，２３４で示されているリードと２３６，２３８で示されている非導電性ピンが延び、これらの双方はマザーボードに係合する。また、ハウジングは、溝２１５の延長部である溝２４１を有する第１垂直部材２４０と、溝２１５の延長部である溝２４３を有する第１垂直部材２４２とを含んでいる。垂直部材より厚さが厚いタブ２４４，２４６が、垂直部材から垂直方向を上方にそれぞれ延びている。また、溝２４１，２４３が、これらのタブを垂直方向に貫通する。最後に、エッジコネクタは、全体が符号２５２で示された第１ラッチ部材と全体が符号２５４で示された第２ラッチ部材とを含んでいる。これらのラッチ部材は、第６図から第１１図に示したものとほぼ同一である。第２０図及び第２１図を参照すると、コンタクト部材のそれぞれは、垂直部２８４と円弧状部２８６とこの円弧状部の末端部２８８とを備えている。垂直部は、基部２９０から延びている。この基部から側方にリード２９２が延びている。基部から垂直方向に支持プレート２９４が延びている。この支持プレートから長手方向に突起２９６が延び、支持プレートの反対側に凹部が設けられている。円弧状部の末端部に対向する側の位置において、支持プレートは、末端部支持面３００を有している。この面の目的は、プリント基板が絶縁ハウジングの溝内に挿入されたときに、円弧状部の過度の応力を防止することである。また、支持プレートは、他の凹設面３０２を有している。明らかなように、プリント基板を効果的に、効率的にかつ経済的に固定し、コンタクト部材の円弧状部の過度の応力を防止し、更に、コンタクト部材の軸方向の移動及び抜けを防止するカードエッジコネクタについて説明してきた。種々の図面の好ましい実施の形態に関連して本発明について説明したが、他の同様な実施の形態が使用可能であり、本発明から逸脱することなく、本発明と同様な機能をなすために上述の実施の形態に追加可能であることが理解されるべきである。従って、本発明は、単一の実施の形態に制限されることなく、添付請求の範囲の記載に従ってその幅及び範囲が解釈されるべきである。 Background 1 of the Detailed Description of the Invention] connector invention. FIELD OF THE INVENTION The present invention relates to electrical connectors, and more particularly, to card edge connectors. 2. BRIEF DESCRIPTION OF THE PRIOR ART : Various card edge connectors are known in the art where the leading edge of a printed circuit board is inserted into a longitudinal groove of an insulating housing. In the vicinity of the groove, a plurality of contacts having arc-shaped conductive portions juxtaposed close to the groove are arranged, and when the substrate is inserted into the groove, the conductive pads of the printed circuit board are in contact with the arc of the contact. Touch the part. The edge card connector may use a latch that locks the printed circuit board in the connector. With this structure, the printed circuit board must be firmly mounted in the connector. Accordingly, there is always a need for improvements to latches for securely and efficiently mounting a wiring board within a connector. Another problem that can occur in this device is that when the printed circuit board is inserted into the groove, the contact members are overstressed, resulting in a loss of vertical contact force. . Therefore, there is a need for a means to prevent this excessive stress on the contact members. Another problem is that a number of juxtaposed contacts are inserted into and into the housing in a manner that does not place undue stress on the housing and resist the forces that tend to push the contacts away from the housing. Related to the fact that it must be held firm. Therefore, there is a need for a means for optimally inserting and retaining contacts within a housing. SUMMARY OF THE INVENTION In the card edge connector of the present invention, a latch mechanism is provided on each side of the insulating housing to secure the printed circuit board in place. These latching mechanisms are pivotally coupled to the uprights of the insulative housing and pivot in an arc to engage the tabs on the upright ends of the insulative housing. These vertical tabs are located on opposite sides of the printed circuit board, and when the latch mechanism is pivoted into place, the parallel fingers of the latch mechanism cause the tabs extending above the vertical portion of the insulated housing to face each other. The printed circuit board is pressed inward, and a lateral force directed inward is applied to the printed circuit board to fix the printed circuit board at a predetermined position. The card connector of the present invention also includes a vertical plate extending upward from the base of each contact. The plate has an upper surface opposite the distal end of the arc of the contact to prevent excessive stress on the arc when the printed circuit board engages the contact. A longitudinal projection having opposed longitudinal recesses is also provided on the plate portion of each contact. Each of these projections engages a groove in the housing and serves to guide the contact longitudinally when the contact is first inserted. The projection cooperates with the housing to hold the contact within the housing after final insertion.

Is a side elevational view of a contact member used in the edge connector shown in, FIG. 21 is an end view of the contact member shown in FIG. 20. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS . 1 to 7, the edge connector includes a molded insulative housing 10 which is connected to a first It has an end 12 and a second end 14. The housing also includes a lower side 18, a first lateral side 20, and a second lateral side 22. The entire printed circuit board is indicated by a virtual line with reference numeral 23. The substrate has a front edge 24 engaging a groove in the housing, an upper edge 25 facing the front edge 24, a first side edge 26, and a second side edge 27. The front edge is supported on the substrate mounting portion 28. The printed circuit board has conductive pads (not shown) located along each side of edge 24. Rows indicated by reference numerals 29 and 30 (FIG. 2) are arranged on the opposite side of the groove 15. Each contact or terminal 29 or 30 forms an electrical connection with a corresponding terminal on the conductive pad. Extending from the lower portion of the housing are leads 32 and 34 and conductive locating pins 36 and 38, both of which engage a motherboard (not shown). The housing also has a first upright member 40 aligned with the groove 15 and having a groove 41 of substantially the same width as the groove, and a first upright member 40 similarly aligned with the groove 15 and having a groove 43 of substantially the same width as the groove. And two upright members 42. Tabs 44, 46 extend from each of the members 40, 42. The grooves 41 and 43 penetrate these tabs in the vertical direction. The housing also includes standoffs designated at 48 and 50 that are supported by the motherboard when the housing engages the motherboard. Finally, the edge connector includes a first latch member, generally designated 52, and a second latch member, generally designated 54. Referring to FIG. 5, each tab 44, 46 has a rising rib, for example, a rib 46A, 46B extending near the leading edge of the tab. Upright members 40, 42 each include a split web 45 having portions 45A, 45B. The web is broken so that the opposing portions of the upright members 40 and 42 can move in directions approaching and moving away from each other. On the inner surfaces of the upright members 40 and 42, a pair of V-shaped grooves 47 sized to receive the projections 66 and 68 of the latch mechanism are arranged close to the web 45. Referring to FIGS. 6-11, each of these latching mechanisms includes an upper shank 56 and a lower eject hook 58. The upper shank is provided with side pivoting projections 60, 62 by which the latch mechanism is mounted in holes in the insulating housing. The latch mechanism also includes longitudinal ribs 64, side engaging projections 66,68, fingers 70,72, and side tabs 74,76. Each of the latch mechanisms pivots on the protrusion 60 or 62 from a position engaging the printed circuit board to a rearwardly inclined position off the board. When the latch is in its rear disengaged position, the printed circuit board has its leading edge engaged in groove 15 and each of its side edges engaged in grooves 41, 43 of vertical members 40, 42. So that it is inserted into the housing. Because the web 45 is broken, the grooves 41, 43 are slightly wider than the thickness of the substrate, and the substrate slides easily into the connector. As the printed circuit board is pushed into the slot 15, the board edge 24 engages the eject hook 58 of each latch to pivot the latches on the protrusions 60,62. When the latch pivots, the fingers 70, 72 slide on the tabs 44, 46. The fingers 70, 72 engage the rising ribs 44A, 46A of the tabs 44, 46 and guide these tabs inward, so that the edges of the grooves 41, 43 are opposed to the lateral sides of the printed wiring base plate. Directional side and clamped at this side to firmly hold the printed circuit board in the connector. As the latches move to the closed position, the protrusions 66, 68 fit within the grooves 47 and each latch is locked in the closed position. Further, the latch mechanism includes a head portion indicated by reference numeral 78 as a whole. In the locked position, the front nose 80 of the head engages the recess in the printed circuit board, and the board is properly positioned and locked in place. The latch mechanism is typically operated by finger tabs 82 to rotate the latch and eject the substrate from the connector. Referring to FIGS. 13 and 14, each of the contact members includes a cantilevered contact arm including a vertical portion 84, an arcuate portion 86, and a distal end 88 of the arcuate portion. The vertical portion extends from the base 90, and leads 92 extend from the base in an opposite direction from the vertical portion. A support plate 94 for mounting the terminals in the housing 10 extends laterally and vertically from the base. Preferably, an elongated projection 96 stamped from the support plate 94 extends from a side of the support plate and has a recess 98 on the opposite side of the support plate. At a position facing the distal end of the arc, the support plate has a distal support surface 100 formed at the edge of the support plate 94. The purpose of this surface is to prevent excessive stress on the arc when the printed circuit board is inserted into the groove in the insulating housing. The gap between surface 100 and the tip of distal end 88 is dimensioned such that when the tip moves as a result of substrate insertion, the tip abuts surface 100 before permanent deformation of the contact arm occurs. doing. The outer edge 95 of the support plate has a concave surface 102 having a holding projection 103 at the upper edge and a positioning surface 106 along the lower edge. As can be seen from FIG. 13, the protruding piece 103 is disposed at a position along the support plate 94 in the middle of the length of the protrusion 96 in the longitudinal direction. Each of the contacts 29, 30 is received in a plurality of terminals or one of the contact recesses 107 in the housing of the connector 10. Each recess 107 includes a groove 108 that extends into one of the sidewalls of the recess. The width w of the groove (FIG. 3B) is slightly wider than the width t of the projection 96. The dimension s for positioning the upper portion of the protrusion 96 is preferably determined so that the upper portion of the protrusion 96 is arranged above the groove 108 when the contact is at the final position. The groove 108 extends from the bottom surface 18 toward the upper surface 16 and is substantially aligned with the direction in which the substrate 23 is inserted into the substrate receiving groove 15. The protrusion 96 and the groove 108 interact in the following manner. When a force is applied to the contacts 29, 30 for insertion into the housing 10, they are arranged with the projection 96 inserted into the groove 108. Because the groove is slightly wider than the protrusion, the protrusion slides in the groove until the protrusion 103 engages the substrate rest 28. By appropriately setting the height h of the protrusion, the longitudinal outer surface of the protrusion is lightly supported by the bottom surface of the groove 108 to generate a relatively small lateral force, and the opposite side of the support plate 94 is It is supported by the side wall of the concave portion 107 facing the groove 108. As a result of the lateral forces, sufficient axial retention occurs to hold the terminals within the housing prior to final assembly. After the final assembly, the contact is firmly held in the housing by the combined effect of the holding force and the holding force formed by the projection 103. This retention is achieved without large lateral forces along the longitudinal axis of the housing that accumulate along the row of contacts and can cause distortion of the housing. The cooperation between the protrusion 96 and the groove 108 allows the contact to be pre-positioned and properly positioned for final insertion. This is particularly useful for manual insertion. When all contacts have been loaded in this manner, all contacts can be pushed into the final position of each recess 107 in the final position, for example, using a final insertion step using an air cylinder. At the final position, the positioning surface 106 is arranged on the step portion 28 a of the substrate mounting portion 28. It should be understood that the hollow projection 96 is observable as a simple support structure whose ends are coupled to the support plate 94. The elongated projections provide a limited lateral force, thereby limiting the risk of the contacts applying stresses to the housing that can cause distortion. Referring to FIGS. 16-19, a second embodiment of the edge connector includes a molded insulative housing 210 having a first end 212 and a second end 214, the ends of which are formed. Are connected by a groove 215 on the upper side 216 thereof. The housing includes a first lateral side 220 and a second lateral side 222. A right angle portion 221 having a proximal portion 218 extends below the housing. The printed circuit board indicated generally by 223 is indicated by phantom lines. The substrate has an upper edge 225, a first edge 226, and a second edge 227 facing a front edge 224 that engages a groove in the housing. This front edge is supported on the substrate platform 228. As in the normal case, the printed circuit board has conductive pads connected to contact members indicated by 229 and 230, which are arranged on opposite sides of the groove. Extending from the base of the right angle are leads shown at 232 and 234 and non-conductive pins shown at 236 and 238, both of which engage the motherboard. The housing also includes a first vertical member 240 having a groove 241 that is an extension of the groove 215, and a first vertical member 242 having a groove 243 that is an extension of the groove 215. Tabs 244 and 246, which are thicker than the vertical members, extend vertically upward from the vertical members, respectively. Also, grooves 241 and 243 penetrate these tabs in the vertical direction. Finally, the edge connector includes a first latch member, generally designated 252, and a second latch member, generally designated 254. These latch members are substantially the same as those shown in FIGS. Referring to FIGS. 20 and 21, each of the contact members includes a vertical portion 284, an arc-shaped portion 286, and an end portion 288 of the arc-shaped portion. The vertical portion extends from base 290. Leads 292 extend laterally from the base. A support plate 294 extends vertically from the base. A protrusion 296 extends in the longitudinal direction from the support plate, and a recess is provided on the opposite side of the support plate. At a position facing the distal end of the arc, the support plate has a distal end support surface 300. The purpose of this surface is to prevent excessive stress on the arc when the printed circuit board is inserted into the groove in the insulating housing. The support plate has another concave surface 302. As can be seen, the printed circuit board is effectively, efficiently and economically secured, preventing excessive stress on the arcuate portions of the contact members, and further preventing axial movement and detachment of the contact members. A card edge connector has been described. Although the present invention has been described with reference to the preferred embodiments of the various drawings, other similar embodiments can be used to perform the same functions as the present invention without departing from the present invention. It should be understood that it can be added to the embodiments described above. Therefore, the present invention should not be construed as limited to the single embodiment, but should be construed in breadth and scope in accordance with the appended claims.
